Answer:

$\huge{\boxed{\sf{15.71 cm}}}$

Step-by-step explanation:

Given :

diameter ( d ) = 5 cm

radius ( r ) = $\frac{5}{2}$ = 2.5 cm

Finding the circumference of a roll of tape:

Circumference of a circle = 2πr

circumference = $2 * \frac{22}{7} * 2.5$

circumference = 15.71 cm

Hope I helped!

3−2x=2x+3(6−3x)−7(1−2y)=25+6y

Zielflug [23.3K]

Answer:

Step-by-step explanation:

First you need to use the distributive property:

3-2x+2x+3(6-3x)-7(1-2y)=25+6y

3-2x=2x+18-9x-7+14y=25+6y

3-2x=-7x+11+14y=25+6y

Then Split up the equations.

3-2x=-7x+11

Subtract 3 from both sides

-2x=-7x+8

Then add -7x to both sides

5x=8

Then divide both sides by 5x

X= $\frac{5}{8}$

To solve for y: just use 14y=25+6y

Subtract both sides by 6y

8y=25

Then divide both sides by 8y

y= $\frac{25}{8}$

Answer:

x = y²

Step-by-step explanation:

Given

x = $e^{2t}$ and y = $e^{t}$

Note that

x = $e^{2t}$ = $e^{t}$ × $e^{t}$ = y²

Thus x = y²

Help please!!! A bag contains 50 marbles, 10 of which are blue, 8 are red, 20 are green, and 12 are purple. Marcie takes a marbl

Andru [333]

Answer:

Step-by-step explanation:

We would need to multiply the number of trials (which is 500) by the probability of choosing a red in 1 try from the information given.

There are 50 in total, and 8 of them are red, so:

P(red) = $\frac{8}{50}=0.16$

Now we multiply this with 500 to get:

$500*0.16=80$

The correct answer is A.

Kelly has 4 times as many songs on her music player as Lou. Tiffany has 6 times as many songs on her

Novosadov [1.4K]

Answer:

113

Step-by-step explanation:

we need to know how much Lou has first !

so we have to do 682 / 6 which = 113

then 113 / 4 = 28.2

28.2 is how much Lou has

so we will go back and multiply the 4

28.2 x 4 =113
